AI-powered talent marketplace connecting experts with frontier AI work
Machine-learning models screen and match candidates to remote roles in hours rather than weeks, based on skills, experience and availability.
AI-driven interviews and assessments validate professional expertise before experts are surfaced to hiring partners.
Experts work on flexible, remote projects with rates reported to average around $90 per hour and fast, recurring payouts.
Mercor collaborates with enterprises to design benchmarks such as legal, accounting and software-engineering evaluations for AI agents.
Proving grounds for agents and engineers who ship real work.
Build realistic networks — web apps, file shares, databases and internal hosts — for training and evaluating offensive-security agents under rules of engagement.
Load any open model, run it offline on your own GPU, inspect which neurons fire per word, then edit and serve the modified model via an OpenAI-compatible API.
Work across repositories, talk to your code by voice, and let agents plan, edit, test and open pull requests from the browser, with every session traced and scored.
Agents search engineers' real work across GitHub and LinkedIn and score candidates against the role, producing a ranked shortlist with evidence.
